Farsight vs PortScan.com
Both stand on port scanner software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Linux
Farsight combines configurable SYN scanning with historical targeting and banner collection, but deployment requires several technical dependencies. Its current scope is IPv4, and Minecraft Server List Ping is its sole implemented application protocol.

PortScan.com offers fast and deep checks of the requesting public IP, with API access and automation options. Treat its results as a basic port check rather than a security audit.
